There is currently a $10 Mail in Rebate for Crest Whitestrips. I have always wanted to try these, but I never want to pay the price for them even when they are on sale. If you can combine the $10 rebate with a store sale and other deals, I'm sure you could score an even better price. Information about the rebate is on 3DWhite.com. If you get the P&G insert, there is an ad for the mail in rebate in there as well.
